What is kinesiophobia after knee replacement?

It is an excessive fear of moving because you expect pain or reinjury. The review's authors say it affects roughly 21% to 35% of people after total knee replacement.

Did exercise-based rehab reduce pain after knee replacement?

Possibly in the first few weeks, but that result was not reliable: it disappeared when one in-hospital trial was left out.

After total knee replacement, exercise-based rehabilitation programs were linked to less fear of movement and better knee function than routine post-surgery rehab. The systematic review and meta-analysis was published in BMC Musculoskeletal Disorders.

What was studied

Kinesiophobia means an excessive fear of moving because you expect pain or reinjury. The authors note it affects about 21% to 35% of people after total knee replacement and can hold back recovery. They wanted to know whether structured exercise-based rehab reduces this fear more than usual post-operative care.

The team searched 11 databases up to July 2026 and pooled 11 randomized controlled trials involving 1,096 adults having a first total knee replacement. The main outcome was kinesiophobia; they also looked at knee function, pain, balance, time to getting up and moving, and how well people stuck with the program.

Key findings

Exercise-based rehab was associated with a large reduction in fear of movement, mainly in the first four weeks.
It was also associated with better knee function, with the clearest result at 12 weeks.
An early pain benefit was possible, but it did not hold up once a single in-hospital trial was removed.
The authors rated the certainty of evidence as low.

What it means for people with knee pain

If you feel nervous about bending or loading your new knee, that is common, and an active, structured exercise program may help you feel more confident and recover function. Ask your surgeon or physical therapist about a guided exercise plan and tell them if fear is holding you back.

Limitations

The trials differed a great deal in their programs and results (very high heterogeneity), several had risk of bias, and the effect sizes shifted when individual studies were removed. Some time-point results could not be interpreted at all. The authors call for larger, well-blinded, multicenter trials.
